Oh! Man those are the best. You have to get a bunch of your friends (try to include some chicks if you can - however, they usually don't go for this sorta thing), and go out there at midnight (make sure there is no moon out - make's it darker).
Before you take off for the 'haunted insane asylum' make sure you guys tell scary stories for about two hours before. You want to be scared, forget Friday the 13th or Jason movies. Go and do this, and I'm telling you you'll find out who are the scary cats.
When I was 14 I was so scared (I used to hang out with a bunch of 18-22 year olds) I almost crushed some guys hand. Yeah, I was so freaking scared I wanted to hold someone else's hand, in my fear I started to squeeze this poor guys hand (don't feel too bad for him, cause they were playing a prank on me) and he had to tell me to ease up on his hand.
When one of the guys pretended to be possesed by a spirit I took off running like a little girl. They kept telling me to wait for them. Yeah! Right, I was like a block ahead of them running like a madman.
Then about a month later a large group went, and this time it was a full moon, which suprisingly didn't make it as scary 'cause you could see pretty far off. Also there were like 10 or 15 people on this trip. What scared the crap out of us, was this large crane (the bird) took off out of the woods and swooped over our heads.
In these you also find the guys that can run the fastest. I was never the fastest runner in competitions. My best buddy was much faster than, I was. Unless, I was scared. I was always at the front of the line - Adrenaline kicks in and forget it - save your self buddy. He he he. Man those were crazy times.
